Structural organization of the rat luteinizing hormone (LH) receptor gene.
The luteinizing hormone (LH)/human chorionic gonadotropin (hCG) receptor gene was isolated from rat liver genomic libraries and spanned at least 75 kilobase pairs from nucleotide -2057 of the 5'-flanking region to the 3'-noncoding end. The structural configuration of the coding region of the LH receptor gene consists of 11 exons separated by 10 introns that are all located within the putative e...
متن کاملChemosensory Stimulation of Luteinizing Hormone (LH)
22 Male Siberian hamsters (Phodopus sungorus) housed in long days (LD), but not short 23 days (SD) release luteinizing hormone (LH) when exposed to females. This study examined 24 whether this response is specific to a female and identifies the source of a stimulus that induces 25 LH release. Serum concentrations of LH, testosterone (T), follicle stimulating hormone (FSH), 26 and cortisol were ...
متن کاملPurine amplification of luteinizing hormone action in ovarian luteal cells.
Adenosine produced a severalfold amplification of luteinizing hormone (LH)-stimulated cAMP accumulation and progesterone secretion in rat luteal cells, but showed no similar effect on LH-stimulated cAMP accumulation and androgen secretion in Leydig cells. In the absence of LH, adenosine produced a small but significant stimulation of cAMP accumulation and steroid secretion in both luteal and Le...
متن کاملExpression of Luteinizing Hormone (LH) Subunit Genes in Mouse Testis
Gonadotropins are heterodimers consisting an alpha chain (Cgα) and a beta chain. Interestingly, presence of complicated LH-β transcripts in rat testis was accidently found; testicular LH-β transcripts were confined in seminiferous tubules to spermatids, and the translated products were localized in the elongated spermatids. We hypothesized that mouse testis has potential to produce the tissue s...
متن کاملExpression of luteinizing hormone/human chorionic gonadotrophin (LH/HCG) receptor mRNA in the human ovary.
The gonadotrophins follicle stimulating hormone (FSH) and luteinizing hormone (LH) are key hormones in the regulation of ovarian function. In the present study, the expression of LH/human chorionic gonadotrophin (HCG) receptor mRNAs in the human ovary was examined. Northern blot analysis was used to measure relative amounts of LH/HCG receptor mRNA, and in-situ hybridization was used to localize...
